[Question] Provide Monthly or Live Power Usage?

[LunarstarPony]

So I'm a little bit confused on this for some reason, what should I provide exactly?

Do I provide the live Energy data or? Currently I have a Total Energy, Total Power, and a Daily Energy that just combine ch1 and ch2. Do i need a New Sensor added on esphome for this?

[LunarstarPony]

Tried to provide daily energy which doesn't seems to work since it will just reset back to 0 everyday, do I need a Specific Sensor that will reset itself every 2 month?

Sorry for feedback delay.

This program use "real time kWh" sensor, NOT the "normally accumulated kWh" sensor!

[Modified] In your case, you should follow document "Appendix II: How to convert from W to kWh", to convert your Ch1 or Ch2 "110V Power (W)" to "real time kWh" sensor, and use this real time kWh sensor as the program input. and follow "Appendix I" convert this kWh sensor to "Utility Meter" sensor as input sensor.

If you test and results are normal, then you can close this issue, or if about one week without any feedback, will close this issue also.

Everything seems to work correctly until I update to the latest version which doesn't seems to be providing value anymore?

Dis

[LunarstarPony]

This is after reconfigure the addon to remove old unavailable devices tho

[cnstudio]

Please try to uninstall, reboot Home Assistant and install (upgrade to v0.53.5) this program again?

[LunarstarPony]

Sadly it still provide nothing atm

[cnstudio]

May I know the status of below questions: 1) What HASS and HACS version you using now? 2) Did you setting input sensor and last bill start date (with setting UI)? 3) Remind input sensor must be "utility meter" sensor type, follow document "Appendix I" steps.

[LunarstarPony]

Core:2024.8.2 Supervisor: 2024.08.0 OS: 13.1 Frontend: 20240809.0 HACS 2.0.0 Everything should be the latest

Input Sensor is set yes

I think this is correct maybe? Or did I did something wrong :v

[LunarstarPony]

[cnstudio]

First please upgrade to v0.53.7 for setup command repair. Then your sensor.bimonthly_energy is use the Appendix 1 step to convert to utility meter from your sensor.total_power?

[LunarstarPony]

So I should Convert the Wattage from my existing setup to kWh using Appendix 2 (sensor.total_power)first and then use the Appendix 1 to convert sensor.total_power into sensor.biomonthly_energy?

And Provide the sensor.biomonthly_energy to Taipower, Correct?

[cnstudio]

It's correct, and... If you wattage sensor is NOT update every second, than you can use normal kWh sensor (as your case is "CHx 110V Energy") for the utility meter input (Appendix 1), and use that utility meter as Taipower input (UI first row).

[LunarstarPony]

atm the 2 PZEM-004T is set to update every 6 second, I could probably decrease that?

[cnstudio]

Hmm... PZEM... so you coding ESPHOME program by yourself? :) If you can adjust that, I suggest you tune the wattage update time to every second for better accuracy and better automation control (like you can use wattage to judge air conditioner is running or stop than to trigger some other things).

But I think 5~6 seconds is meet "minimum requirements".

Yeah I just change it to 1s here's the currect ESPHome Config xd

[cnstudio]

Ha, that's great! then you will got very accurate results. :)

[LunarstarPony]

I'll give it a go c:
